WebOrientation of a crystal plane in a lattice is specified by Miller Indices. These are denoted as h,k & l (the plane is denoted as (hkl) ). These are defined as the reciprocal of the intercepts by the plane on the axes. This is an online tool to visualise a plane associated with a specific set of miller indices. Web1 day ago · The standard IPF map was used, which depicts three primary crystallographic directions within grains (red – <001>; green – <101>; blue – <111>; refer to the inset of the small IPF triangle legend in the IPF maps). Kernel average misorientation (KAM) maps were used to estimate grains' plastic strain or deformation magnitude.
